Accounts not prepared on a going-concern basis
subsequent to 31 December 2024, the Company's trade, assets and liabilities were transferred to a fellow group company following a group reorganization and accordingly the directors have prepared the financial statements on a basis other than going concern. Furthermore, as the company's parent entity has agreed to provide financial support to ensure all liabilities can be met as they fall due, these financial statements do not include any adjustments resulting from the non-going concern basis.
